[0002] During the production processes of chemical, metallurgical, steel, and energy industries, a large amount of harmful gases are generated. These gases need to be treated before they can be discharged. Chimneys play a vital role as the final emission channel. Existing chimneys mainly come in two forms: one is an outer-tube inner-tube structure, where the outer tube provides structural strength and the inner tube provides corrosion protection. However, with this type of chimney, the outer tube obscures observation, making it impossible to observe the inner tube and detect problems in the inner tube in a timely manner. The other type is a tower inner-tube structure, where the tower provides structural strength and the tower-type hollow structure facilitates observation of the inner tube. However, this type of chimney has been found to have the following problems during long-term use: due to the multiple points of rigid contact between the tower and the outer surface of the inner tube, when the chimney undergoes thermal expansion, the outer surface of the inner tube at the contact point will be damaged, thereby reducing the service life of the chimney and increasing the occurrence of accidents. In addition, existing chimneys are more troublesome to clean their interior, and the energy recovery rate is also low. Summary of the Invention

[0024] refer to Figure 1 and 2 As shown, an embodiment of the present invention provides a tower-type sleeve chimney that is easy to maintain, including a chimney body 1 and a tower body 2.

[0025] The chimney body 1 is composed of multiple chimney segments 11 connected in sequence. The chimney segments 11 can be prefabricated, and each chimney segment 11 can be made into a length of about 10 meters. In this embodiment, the chimney segments 11 are prefabricated, which is a method of high production efficiency, low cost, high quality, and high specification consistency. Adjacent chimney segments 11 are connected by chimney flanges, which effectively ensure the sealing and stability of the connection and also ensure easy assembly and disassembly.

[0026] Near the lower end of the chimney body 1 are located a drain pipe 12, a dust cleaning door 13, and a flue gas inlet 14. The dust cleaning door 13 is located higher than the drain pipe 12, and the flue gas inlet 14 is located higher than the dust cleaning door 13. A sampling window and a detection tube are also located near the middle of the chimney body 1. A rain cap 15 is installed at the upper end of the chimney body. The rain cap 15 is detachably connected to the chimney body, for example, with bolts, for easy assembly and disassembly.

[0027] A wind turbine 16 is further provided at the upper end of the chimney body 1, and the wind turbine 16 is located below the rain cap 15. Since a large airflow is generated at the smoke outlet when the chimney body 1 discharges smoke, the airflow can drive the wind turbine 16 to generate electricity, thereby greatly improving energy recovery and utilization.

[0028] The tower body 2 is composed of multiple tower segments 21 connected in sequence. The tower segments 21 can be prefabricated or welded on-site. Each tower segment 21 can be manufactured in lengths of approximately 10 meters. In this embodiment, the tower segments 21 are prefabricated, which provides high production efficiency, low cost, high quality, and high specification consistency. Adjacent tower segments 21 are connected by tower flanges, which ensures good connection stability and convenient assembly and disassembly.

[0029] The tower section 21 includes columns 211, fixing rings 213 and reinforcing rods 212. There are multiple columns 211, and the multiple columns 211 are evenly distributed along the circumference of the fixing ring 213. Multiple fixing rings 213 can be set along the length direction of the column 211. The fixing ring 213 and the column 211 can be welded or bolted. Multiple reinforcing rods 212 are cross-arranged between two adjacent columns 211. The two ends of the reinforcing rod 212 are respectively connected to the two adjacent columns 211. The reinforcing rod 212 and the column 211 can be welded or bolted. The arrangement of the reinforcing rod 212 greatly improves the structural strength of the tower section 21.

[0030] The tower body 2 is disposed outside the chimney body 1 and is provided with a ladder 3 extending from the lower end of the tower body 2 to the top thereof, making it convenient for operators to climb and perform inspections and maintenance. The ladder 3 can have either a spiral or straight-climb structure. In this embodiment, the lower half adopts a spiral structure because the lower half is climbed more frequently. The spiral structure is convenient and safe to climb. The upper half adopts a straight-climb structure because the upper half is climbed less frequently. This structure is low in cost, lightweight, and easy to install.

[0031] The tower body 2 is further provided with a sampling platform 4 at the height of the sampling window and the detection tube of the chimney body 1. The sampling platform 4 can be entered through a ladder 3, and sampling operations can be performed by standing on the sampling platform 4.

[0032] An inspection platform 5 is provided on the top of the tower body 2. The inspection platform 5 can be entered by climbing a ladder 3. Standing on the inspection platform 5, the internal situation of the chimney body 1 can be observed, and the top can also be inspected.

[0033] The maintenance platform 5 is provided with a maintenance hoisting support mechanism 51, Figure 3As shown, the maintenance hoisting support mechanism 51 includes a support column 511, a beam 512 and a lifting trolley 513. There are two support columns 511 and they are symmetrically arranged on both sides of the chimney body 1. The lower end of the support column 511 is detachably connected to the maintenance platform 5. The two ends of the beam 512 are respectively connected to the upper ends of the two support columns 511. The lifting trolley 513 is arranged on the beam 512. The lower end of the lifting trolley 513 is used to hang a dust cleaning robot. The lifting trolley 513 can adopt existing technology. The dust cleaning robot also adopts existing technology, such as a wall-climbing robot. The wall-climbing robot is provided with a cleaning brush. Since the chimney body 1 is made of steel, the wall-climbing robot can climb inside the chimney body by magnetic attraction to perform dust cleaning operations.

[0034] When cleaning operations are required, first remove the rain cap 15 and the wind turbine 16 on the upper end of the chimney body 1 and place them on the maintenance platform 5, then hang the cleaning robot on the lower end of the lifting rope of the lifting trolley 513, and place it into the chimney body through the lifting trolley 513, and then control the cleaning robot to clean the interior of the chimney body 1 according to the set route.

[0035] There is a gap between the tower body 2 and the outer circumference of the chimney body 1, which can effectively compensate for the thermal expansion of the chimney body 1 and reduce the damage caused by the relative displacement between the chimney body 1 and the tower body 2. Of course, in order to improve the relative stability between the tower body 2 and the chimney body 1, a tightening mechanism 6 can be set on the tower body 2. The number of tightening mechanisms 6 is multiple groups, which are distributed at intervals along the circumference and height directions of the chimney body. Specifically, at the same height position of the chimney body 1, multiple groups of tightening mechanisms 6 are evenly distributed along its circumference to form a circle, and multiple circles of tightening mechanisms 6 are set at intervals along the height direction of the chimney body 1.

[0036] refer to Figure 4 As shown, the tensioning mechanism 6 includes a base 61, a spring 62, and a top plate 63. The base 61 is mounted on the tower body 2. A mounting hole is provided at one end of the base 61, which is adjacent to the chimney body 1. The spring 62 is positioned within the mounting hole, with the front end of the spring 62 extending out of the mounting hole. The top plate 63 is positioned at the front end of the spring 62, and the top plate 63 supports the outer surface of the chimney body 1. When the chimney body 1 undergoes thermal expansion, all springs 62 in the tensioning mechanism 6 are compressed, compensating for the expansion and ensuring that the top plate 63 always supports the outer surface of the chimney body 1. When the chimney body 1 sways due to natural environmental factors, the springs 62 in the tensioning mechanism 6 in the corresponding direction are compressed, while the springs 62 in the opposite direction are extended. This compensates for the displacement of the chimney body 1 and also acts as a buffer, effectively protecting the chimney body 1 from damage caused by shaking and collision, thereby significantly increasing its service life.

[0037] In order to better protect the chimney body 1, a protective plate 64 is provided on the outer surface of the chimney body 1 at the contact position with the top plate 63. The protective plate 64 can be made of metal material or wear-resistant material. The top plate 63 abuts against the protective plate 64, so that the wear of the chimney body 1 can be greatly reduced when it expands or swings due to heat.

[0038] The tower-type sleeve chimney provided by the embodiment of the present invention, which is convenient for maintenance, can be installed in the following two ways, which can be selected according to the actual situation: 1. First, assemble each chimney section 11 and tower section 21 together in the factory or at the construction site, and then hoist and splice the two together from bottom to top. The adjacent chimney sections 11 are fixed together by chimney flanges, and the adjacent tower sections 21 are fixed together by tower flanges. Finally, install the ladder 3, sampling platform 4 and maintenance platform 5.

[0039] 2. Transport the prefabricated chimney section 11 and tower section 21 to the construction site, then hoist the chimney section 11 and tower section 21 respectively. After installing one chimney section 11, hoist the corresponding tower section 21 onto the periphery of the chimney section 11. The two adjacent chimney sections 11 are connected and fixed by chimney flanges, and the two adjacent tower sections 21 are connected and fixed by tower flanges. Finally, install the ladder 3, sampling platform 4 and maintenance platform 5.

[0040] The present invention is not limited to the above-mentioned optional implementation modes. Anyone can derive other forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, any technical solution that falls within the scope defined by the claims of the present invention falls within the scope of protection of the present invention.
